The Kandy Machine is light gray in color with many red buttons at the bottom of it. There is a glass window near the top that displays the variety of snacks inside. The word "Kandy" is also located at the very top as a neon pink sign. The letter "N" on the sign is backwards.
Role in series
The Kandy Machine is located right across the bus stop in Rock Bottom. After SpongeBob gets stuck in Rock Bottom and fails to satisfy his hunger with his Candy Glove, SpongeBob spots the Kandy Machine across the street and wants to get some Kelp Nougat Crunch. However, every time SpongeBob tries to go to the machine, the Bus will arrive at the bus stop and then leave before he can get to it. Eventually, SpongeBob is able to buy the Kelp Nougat Crunch bar, but the bus ends up leaving him as usual. Someone then comes and takes SpongeBob's Kelp Nougat Crunch bar from the Kandy Machine.
In the levels "Road to Rock Bottom" and "Lonely Souls," the goal is to find the Kandy Machine in order to get some candy. However, both Kandy Machines are empty, to SpongeBob's annoyance.

The Kandy Machine reappears in the Rock Bottom level of Battle for Bikini Bottom. If SpongeBob goes near it, a bus will pull up and leave, referencing the aforementioned episode.
SpongeBob's Boating Bash
The Kandy Machine reappears in the Rock Bottom arena as a decoration.
